Title: Mass flowmeter with temperature sensor
Inventor: FUREDERITSUKU FUAN DERU GURAAF
IPC: G01F1/69
Filed: 1990-02-22
Abstract: PURPOSE: To accurately measure the flow rate of a medium by eliminating a zero offset by reducing the temperature difference between temperature sensors symmetrically arranged with respect to heating elements constructed in double structures to nearly zero before making the fluid to flow by using the heating elements. CONSTITUTION: At the center M of a metallic casing 2 through which a medium to be measured flows, heating elements 5 and 6 constructed in double structures are arranged and three joints for power supply are provided so that the elements 5 and 6 can be controlled separately. When the fluid does not flow through the casing 2, the fluid is heated so that the temperature difference between two temperature sensor 7 and 8 which are symmetrically arranged with respect to the center M can become zero. When the fluid flows through the casing 2, the temperature of the fluid on the upstream side of the center M becomes lower and that on the downstream side becomes higher. Therefore, the flow velocity, namely, the mass flow rate of the fluid can be found accurately from the temperature difference by eliminating a zero offset.

Title: Adjustment of powder sample for analysis
Inventor: TERAI YOICHI
IPC: G01N23/22
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To prevent the cracking of a sample caused by the expansion of voids by introducing a powder sample into a frame body having pores smaller than the particle size of the powder sample formed to the entire surface thereof to mold the same under pressure. SOLUTION: Since a powder sample 6 to be subjected to pressure molding is degassed from the entire surface thereof by the pores 2 smaller than the particle size of the sample 6 provided to a frame body 1, closed voids 5 are extremely reduced. That is, mutual voids have piercing properties of a certain degree by piercing passages 3 and, by degassing the sample from the entire surface thereof, almost all of large voids 4 piercing the entire surface are degassed. Since the sample 6 is held from an aspect of strength by the frame body 1, the cracking of the sample is hard to generate during degassing. Further, even if fine voids 5 are generated by the reduction of a binder, a molded object is degassed from the entire surface thereof through the pores 2 of the frame body 1 and, therefore, the expansion of the voids 5 is suppressed and the generation of a crack can be prevented.

Filed: 1987-02-25
Abstract: PURPOSE:To improve the yield rate in manufacturing, by providing a depletion part including a gap formed by the thermal deformation of a packaging case between the attaching and tightening part of the packaging case and heat radiating fins, and filling the depletion part and the gap with a resin through a narrow slit. CONSTITUTION:A depletion part 28, which is separated from an attaching hole 27, is provided in an attaching and tightening part 26 of a packaging case 23. The depletion part 28 is filled with a resin 24 through a resin injecting path 29, which is communicated to the inside of the case. The gap between the attaching and tightening part 26 of the packaging case 23 and heat radiating fins 21 is filled so as to withstand tightening pressure. Thus cracking of the packaging case 23 at the time of packaging is prevented. Since the resin injecting path 29 is made narrow, the pressure of the resin, which is inputted in the depletion part 28, is largely decreased in comparison with the pressure at the inlet port of the resin injecting path 29, i.e., the pressure of the resin at the inner wall of the case. Therefore the resin does not leak to the outside through the depletion part 28.
